DNMG150412-MW5 WKK10S turning indexable insert — Tiger·tec Silver coating, for cast iron (Walter Tools)

A DNMG150412-MW5 WKK10S turning insert engineered for stable finishing and semi-finishing of cast iron components in demanding production environments.

• Tiger·tec Silver coating technology
• WKK10S grade for cast iron machining
• MW5 chipbreaker for stable chip control
• 1.2 mm corner radius, Rhombic 55° shape

Consistent chip control for efficient cast iron turning

The insert combines the MW5 chipbreaker with the WKK10S wear-resistant grade to manage the short, brittle chips typical of cast iron. The chipbreaker geometry reduces the risk of chip entanglement and ensures predictable breakage, which supports consistent cycle times. Because the grade and breaker are matched to abrasive wear conditions, tool changes are less frequent and process stability is improved. This makes the insert particularly suitable for repetitive production where uptime matters.

Edge stability and wear resistance that extend cutting intervals

The Tiger·tec Silver coating increases resistance to abrasive wear while maintaining a sharp cutting edge for longer. The 1.2 mm corner radius contributes to a stronger edge for interrupted cuts and small depths of cut, reducing the likelihood of chipping during heavy engagement. The Rhombic 55° form provides a balance between approach angle and strength, enabling versatile use across finishing and light roughing operations. As a result, surface quality and dimensional consistency benefit from reduced edge degradation.

Easy integration and predictable tool behaviour in the toolroom

Marked as DNMG150412-MW5, the insert is compatible with standard toolholders designed for rhombic 55° turning inserts and is manufactured to tolerance class M for consistent seating and clamping. The negative 0° rake angle supports a robust cutting edge suited to the intermittent cutting conditions often found when machining cast iron. The standardised geometry and thickness designation allow straightforward inventory handling and quick replacement without complex reprogramming, helping to keep machine downtime to a minimum.

FAQ

What makes the WKK10S grade suitable for cast iron?
The WKK10S grade is a coated carbide formulation within the Tiger·tec Silver family that is optimised for the abrasive wear and short-chip behaviour of cast iron, providing improved wear resistance and stable cutting performance.

Which chip control behaviour can be expected from the MW5 chipbreaker?
The MW5 chipbreaker promotes short, segmented chips when turning cast iron, improving chip evacuation and reducing the risk of entanglement in automated or manual machining environments.

Does this insert fit standard DNMG toolholders?
Yes, the DNMG150412-MW5 geometry corresponds to standard rhombic 55° DNMG inserts and is intended for holders designed for that form factor; tolerance class M supports reliable seating.

How does the 1.2 mm corner radius affect surface finish?
A 1.2 mm corner radius strengthens the cutting edge for interrupted cuts and contributes to a consistent surface finish in finishing and light semi-finishing passes while extending edge life.

Is the insert intended for roughing or finishing operations?
The combination of negative 0° rake, 1.2 mm corner radius and the WKK10S grade makes the insert versatile for finishing and light semi-roughing on cast iron; for heavy roughing, alternative geometries may be preferred.
